The iNaturalist Network is a localised experience that is fully connected to the global iNaturalist community. Network members are local institutions that promote local use and facilitate the use of data from iNaturalist to benefit local

The aim of this report is to give an account of the importance of the iNaturalist network members by analysing the number of records for each country.

Methods

We tested different explanatory variables and saw which is the model that best explains the values a country has for iNaturalist.

Response variables:

  • total number of records on iNaturalist per country: n_records_inat.
  • number of records from iNaturalist on GBIF per country (proxy for quality, research grade records): n_records_gbif_iNat.
  • number of users recording in the country (this is not exactly the users from the country, but users that have generated records in the country): n_users.

Explanatory variables:

  • population of the country: population.
  • area of the country in km2: area.
  • country’s centroid latitude (as a proxy of expected biodiversity): latitude.
  • human development index: hdi.
  • GDP per capita: gdp_per_capita.
  • % of the GDP of the country dedicated to research: gdp_research.
